3. Move the Tx throttle stick to the desired position for the
throttle control to move if the Rx goes to failsafe.
4. Press and hold the “Bind” button on the receiver, and the
Rx’s LED should blink twice. Release the Bind button,
and the receiver’s LED should turn on (stop fl ashing).
The Tx and Rx should now be bound, with the throttle
failsafe in the new position as set above.
NOTE: If you’re using an ESC which has a signal loss feature,
the pre-set failsafe position is irrelevant as the signal loss feature
will cease the throttle operation if the signal is lost.
SYSTEM CHECK AND OPERATION
WARNING! During all pre-fl ight preparations with
the aircraft on the ground, make sure the throttle
stick remains at the minimum position and do
not stand the Tx upright on the ground. Carefully
lay the Tx on its back on the ground to prevent it from falling
over and possibly dislodging the throttle stick from the low
position which would create a safety hazard. Make sure all
devices are properly mounted inside the model, and all wiring
connections are solid to prevent them from easily becoming
dislodged during normal fl ight. It’s best to check the system
with the propeller removed from the aircraft.
1. Once all connections are made, check the general
operation of the radio and all other components before
attempting a fl ight.
2. Move the Tx throttle stick to the minimum (idle) position.
3. Turn on the Tx, and then the Rx.
4. Make sure all controls are operating in the proper
direction. If any servo is turning in the wrong direction,
change the position of the reversing switch for that
particular channel.
5. With both sticks at center position, move the trim levers
for the aileron, elevator, and rudder channels so each
respective control surface is perfectly aligned with the
main surface. For example: When the aileron trim lever
is in the center position, it’s best that the trailing edge of
the aileron is aligned with the trailing edge of the wing
itself (not above or below the wing’s trailing edge).
6. Make sure that movements of the throttle stick result
in an equal adjustment of the throttle in the model.
Depending on whether the airplane is electric or glow
powered:
a. Electric: confi rm that when the throttle stick is at
maximum position the electronic speed control gives
the appropriate indications (LED and/or audible
indicators) for full forward fl ight. And, when the throttle
stick is at minimum position the electronic speed
control gives the appropriate indications for “off” or
no motor rotation.
b. Glow: confi rm that when the throttle stick is at
maximum position the mechanical linkage to the
engine allows the engine to be at full throttle. And,
when the throttle stick is at minimum position and
the throttle trim lever is moved to minimum position,
the engine stops completely.
7. Perform a “range check.” The “range” is the safe
operating distance from the Tx to the Rx, and should
be as far as you can clearly see the model. With the
assistance of another person, place the aircraft on the
ground and walk 100 feet (30m) away from the model.
With the Tx pointed directly at the model, operate
the transmitter’s controls, and ensure the movement
of all surfaces is according to the movement of the
transmitter.
8. Anytime power is to be removed from the radio system,
it’s important to shut down power in the aircraft fi rst.
Otherwise, the aircraft could become out of control
and cause a safety hazard! Move the throttle stick and
throttle trim lever to minimum position to stop the glow
engine or shut down the ESC. Once the propeller has
stopped rotating, shut off the ON/OFF power switch
in the model, and disconnect the power battery from
the ESC in electric airplanes. Then turn off the power
switch in the Tx.
